alt Hacker NewsThis is entirely within the scope of "recreationally employed". There is no implication that what you spend your time on has anything to do with your former career.
In most cases I know of recreational employment has little to do with their former employment. They often put in a lot of hours and it is still "work" in the ordinary sense but it is entirely self-directed.
I believe it's a misuse of "employment" then, I do not understand employment as something you do without payment, to me it is necessarily related to paid labour.
